Usage

Iterate over an Array

const AsyncIterator = require('asynchronous-iterator');

const array = new AsyncIterator([1, 2, 3, 4]);

array.each((value, index, array) => {
    console.log(value, index, array);
}).then(() => {
    console.log('Finished!');
}).catch(() => {
    console.log('Something went wrong!!');
});

Iterate over a Range

Example 1:

const AsyncIterator = require('asynchronous-iterator');

const range = new AsyncIterator(6);

range.each(index => {
    console.log(index); // 0 - 5;
}).then(() => {
    console.log('Finished!');
}).catch(() => {
    console.log('Something went wrong!!');
});

Example 2:

const AsyncIterator = require('asynchronous-iterator');

const range = new AsyncIterator(3, 6);

range.each(index => {
    console.log(index); // 3 - 5;
}).then(() => {
    console.log('Finished!');
}).catch(() => {
    console.log('Something went wrong!!');
});
